ZP100 not booting

Hi,

I've recently acquired a ZP100 however it looks to be stuck in the boot process with a single white light flashing endlessly.

It doesn't appear responsive to holding the mute button on bootup. On powerup all of the network port light flash briefly and the connection lights are solid if wired to bridge via ethernet.

I know this is an old product and I know it is my fault for purchasing it, but is there any other reset tricks or way to update the firmware to get out of this loop?

    if you hardwire the unit to your router, what do you get when running arp -a in any network device?

    connecting ZP directly to my computer. And computer is set to static ip address of 169.254.1.2/24 default gateway of 169.254.1.1
    Here's the output from arp -a

    arp -a

    Interface: 169.254.1.2 --- 0xb
    Internet Address Physical Address Type
    169.254.255.255 ff-ff-ff-ff-ff-ff static

    apparently, there is no ethernet traffic at all from the unit.
    what happens when you try to factory reset it?
    also, when you connect it to your network, are there any dhcp requests?

    On a working unit, when I hold mute button and plug in the power, the LED eventually flash in amber/orange. After release the mute button, LED eventually shows constant white.

    On this problematic unit, LED continue to flash white immediate after plug in AC. event with me pressing and holding the mute button, LED never change to amber...it continue to flash white.

    I'll take a look at my router log to see if DHCP request is made from the device.

    nothing on router DHCP log. Consistent with no ethernet activity analysis from arp -a

    I press h to get into boot loader menu

    Rincon boot loader version 1.0-27270(ZP) (32M SDRAM). Press 'h' for help.
    h - help
    m - SDRAM test
    i - print NAND device ID
    n - NAND device scan
    x - NAND device destructive test
    y - NAND device dump first page
    p - Program NAND device
    b - Boot the Linux kernel from NAND device
    d - Boot diagnostics from NAND device
    > nand_load: bad page magic, page 0

    There's Boot diagnostics, but press d only result in the bad page magic.

    Does anyone know what this mean? Has anyone try this option with success?

    Never seen that before.
    But as I can see, maybe the nand is fried? 😞

    None of the production units (or indeed the diagnostic unit) that I have worked on have a diagnostic partition. A quick look at the bootloader assembly indicates that it refers to a different type of partition that I've never seen before. My guess is that it is a remnant from the development process (remember that the bootloader wasn't designed for us), that's been left in.

    I have a RAM chip (ISSI IS42S16800A-7TL) ordered on ebay to replace the one that wont boot on its own. I guess I should order another one for the temperature failing one.


    Did you ever get the RAM chip replace? was it easy to do?

    Haven't received the chip from China yet. Replacement, well, there's certainly a technique to replacing a 54 pin SMT chip.

    Would love to see some pic.
